Description

When running an old harness test with a Java 8 preview (available from http://jdk8.java.net/download.html), it'll fail like this:

$ java org.apache.derbyTesting.functionTests.harness.RunTest lang/supersimple.sql
– listing properties –
derby.locks.deadlockTimeout=3
derby.locks.waitTimeout=3
WHOA, javavm is NULL
Process exception: java.lang.ClassNotFoundException: org.apache.derbyTesting.functionTests.harness.jdk18

We need to add the org.apache.derbyTesting.functionTests.harness.jdk18 class to make the tests run on Java 8.
